A eunuch

Scholar Wei looked at Liu Hui Ying who was dressed as Chen Rui and nodded before he cupped his hand and greeted her politely after standing up from his seat, " Lord Chen, I am scholar Wei. You can call me Sir Wei or Master Wei as you like, it is a pleasure to meet you." 

" Likewise," Liu Hui Ying replied but instead of cupping her hand, she stretched her hand in front of Scholar Wei who looked at her outstretched hand dubiously, he turned to look at Zhai Tianyu who nodded but even after receiving his permission, Scholar Wei did not shake hands with Liu Hui Ying. 

Seeing this Liu Hui Ying took Scholar Wei's hand and shook it fervently, " What are you looking at his majesty for, Master Wei? It's just shaking hands why are you acting like you cannot even do that much."
